I just got word that the two will cohost a party next week for a musician pal at their L.A.-area home. The soiree will take place almost exactly a month after the Medium star filed for divorce to end their two-and-a-half-year marriage.

The invite for the party reads, "Thomas Jane and Patricia Arquette Invite You to Their Home to Witness the Spectacular Eric Lewis."

Mr. Lewis, who also goes by ELEW, is scoring Jane's feature film directorial debut, the 3-D horror film The Dark Country.

No word if Arquette has put a stop to the divorce proceedings. Citing irreconcilable differences in documents filed in Los Angeles Superior Court on Jan. 5, Arquette requested sole legal and physical custody of their 5-year-old daughter, Harlow Olivia Calliope, with visitation rights for Jane.

Reps for the two did not immediately comment.

If Arquette and Jane have indeed reconciled, they join a long list of Hollywood uncouplings willing to make another go of it. Check out the Celebrities Breaking Up or Making Up gallery. (Wonder who had the best makeup sex?)
